Question

calcule,indicado o resultado sem radical a) √3×√12 b) 3√2×3√4

Answer 1

a) (raiz² 3)*(raiz² 12)= (raiz² 36) = 6
b)3*(raiz² 2)*3*(raiz² 4)= (raiz² 3*2²) * (raiz² 3*4²)= (raiz² 12) * (raiz² 48)=
(raiz² 576) = 24
     

Answer 2

a) √3×√12 =  √3×12 ==> √36 ==> 6

b) 3√2×3√4 = (3.3)√2.4 ==> 9√8 = 9√2².2 ==> 9.2√2 ==> 18√2
